Poco: Please remove empty directories

[David Stacey]

With the release of poco-1.6.1, I've decided to do some housekeeping and 
remove some of the earlier versions. I've managed to do this, but it has 
left some empty directories lying around. Please could some kind soul 
remove the following:

    x86_64/release/poco/libpoco16/
    x86_64/release/poco/libpoco17/
    x86/release/poco/libpoco17/
Is there a way I can remove directories myself, or should I continue to 
ask here in future?

Many thanks in advance,

Dave.
